The headers are available now...Only for DE though. According to the 370 forums, Z1 said they were working on a set compatible for us HR/VHR guys

Agree, 100%

 

Gawd Damn that car sounds amazing. So good to see developments like this.

 

I think those are it since it does say:

"These headers are built to be a direct bolt on to the VQ35DE, however they can be used on 07+ VQ35HR and VQ37VHR engines with the use of Stock DE Catalytic Converters or with Z1 High Flow Cats or Test Pipes available as an option below."

You just have to use a DE testpipe/HFC/ART/whatever...as long as it's for a DE engine.

 

Correct, but they're working on a direct bolt on for us HR/VHR guys so it'll eliminate the need for us to swap out our current HR pipes for DE parts

 

That's what I wanted to hear...it's a good thing, because I have no money right now.

 

It's a great option for those who still need cats from time to time!

 

So these headers actually produce sufficient amount of power to be worth buying/installing for the HR? c'mon Z1 tells what was done to the Z!!!

 

I still say the tuning, weather/dyno, and supporting mods besides those headers and exhaust helped!

waits for buyer's impressions

 

I like being the guinea pig...

 

Should I be waiting for HR headers to be released, or ordering DE headers and TPs? Z1 what's the scoop?

 

I was about to order the DE version with Z1 test Pipes, But I saw the worse new in the world in the 370Z forum... That they ran out of headers and won't be reviving anymore till some weeks. I AM PISSED!!!!

 

sub'd

 

Currently waiting on my set with Z1 test pipes.

 

So what advantages do these have over long tube such as ppe or maybe even the obx long tube replica ?

 

no body ever done a back to back dyno test yet to prove anything

however I got my hand on a real momentum that I will test later on this year against my PPE.

 

Im pulling the trigger on PPEs today, anything I should know about the HR version of the Z1 headers that would make me hold off on buying PPE?.
I see in a post above it says they fit on an HR but what worries me is that the head flow characteristics of a DE vs HR are a lot different which leads me to believe the header design should be different, any input on this?

 

Should've waited I'm gonna sell my PPEs for $1000 heat wrapped.

 

Stepped or? And when are you gonna put them up for sale? Was sort of waiting on a reply on this thread so I didn't buy today, I will tomorrow morning though.

 

Stepped. And they'll up for sale as soon as I get my Z1 headers and test pipes. Late July not sure on the ETA.
